2AM seems to be the middle of the night. Do you mean that you slept in bed so late that you didn't get enough sleep the following night? If you want advice on good sleep habits, there are lots of useful sites like this one that can give you advice:http://www.sleepeducation.org/essential ... eep-habits

I'm not sure why the Buddha thought those sleeping habits were bad, but most people notice that unless they get the "right" amount of sleep for them, at regular times, they become less efficient, less alert, and bad tempered. I don't know your age, but teenagers apparently need to sleep more and sleep later for optimal health.

This short excerpt is from a question and answer session with venerable Ajahn Chah:

Q: What about sleep? How much should I sleep?

A: Don't ask me, I can't tell you. A good average for some is four hours a night. What is important, though, is that you watch and know yourself. If you try to go with too little sleep, the body will feel uncomfortable and mindfulness will be difficult to sustain. Too much sleep leads to a dull or a restless mind. Find the natural balance for yourself. Carefully watch the mind and body and keep track of sleep needs until you find the optimum. If you wake up and then roll over for a snooze, this is defilement. Establish mindfulness as soon as your eyes open.

To study is to know the texts,
To practice is to know your defilements,
To attain the goal is to know and let go.

- Ajahn Lee Dhammadharo

With mindfulness immersed in the body
well established, restrained
with regard to the six media of contact,
always centered, the monk
can know Unbinding for himself.

- Ud 3.5

Ultimately, your meditation involves sustaining the knowing, followed by continuous letting go as you experience sense objects through the eyes, ears, nose, tongue, body and mind. It involves just this much and there is no need to make anything more out of it.

"There is the case where a monk has some work to do. The thought occurs to him: 'I will have to do this work. But when I have done this work, my body will be tired. Why don't I lie down?'

"A 'position,' Vaccha, is something that a Tathagata has done away with. What a Tathagata sees is this: 'Such is form, such its origination, such its disappearance; such is feeling, such its origination, such its disappearance; such is perception...such are fabrications...such is consciousness, such its origination, such its disappearance.'" - Aggi-Vacchagotta Sutta

I read an article the other day that people that don't get enough sleep are more likely to develop Alzheimers and Dementia, a good nights sleep is something to be valued, for an average person 9 hrs is not excessive, in fact its whats recommended for many people.

18 years ago I made one of the most important decisions of my life and entered a local Cambodian Buddhist Temple as a temple boy and, for only 3 weeks, an actual Therevada Buddhist monk. I am not a scholar, great meditator, or authority on Buddhism, but Buddhism is something I love from the Bottom of my heart. It has taught me sobriety, morality, peace, and very importantly that my suffering is optional, and doesn't have to run my life. I hope to give back what little I can to the Buddhist community, sincerely former monk John

This night my body fell asleep at 9 pm and woke up at 1.3 am (but after meditationand reading suttas, when i put a Dhamma Talk in my ears at 5.3 am, i felt asleep, and does that utill 8 am

While when i was out of practice i slept from 9pm untill 8-10am... and needed an additional effort to get out of bad...

perpetual lack of sleep is not a state of well being unless you naturally feel good with low amount of sleep, forcing yourself to sleep less is not good for you're well being at all.

I also train perception of light, trying to imagine daytime. It seems to have a similar effect on a sleepy mind like sniffing Ammonia or Alcohol would have sort of i don't think maybe people experiment with this training.
